HOOK.

To all whomc't may concern:

Be it known that I, ANsoN E. CARLTON, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Hooks, of which the following is a specification.

In my application for patent for an antiskid device for wheels filed March 20, 1918, Serial No. 223,526, I show on the anchorage member to which an anti-skid chain is at tached hooks with which the ends of the chains are coupled, which hooks have plate springs bearing against their ends at the inside thereof to prevent-the chains from uncoupling. The object of this my present invention is to provide a hook to be used for such a purpose, or any other purpose, in fact, with a novel means to keepa chain link or equivalent coupled therewith from being uncoupled, the same being devised so as to permit greater clearance for the chain link in coupling it with or uncoupling it from the hook and so as to make it more facile to coupleand uncouple the link than the use of a spring makes possible and so that further a substantial and durable device of this kind shall result.

In the drawing, 7

Figure 1 shows the improved hookforming a part of an anti-skid device like that shown in my patent application aforesaid, the wheel to which the device is attached appearing in section;

Figs. 2 and 3 show the hook and a link connected therewith in side elevation, the two figures showing the link in two different positions, and V Fig. 4 is a plan of the hook and the link.

a is an'anchorage member secured to the rim 6 of a wheel and equipped with two i hooks 0 which may be welded thereto or otherwise form rigid parts thereof and are of the common substantially J-shaped type.

d is the anti-skid chain, whose end links 0 are coupled with the hooks 0.

Instead of employing, as in my said application, a plate spring welded to the shank of of each hook and bearing against the innerside of its free end 0 which requires an undesirable spacing of the parts 0 and c from each other in order to afford the necessary clearance forthe link 6 in coupling it with or uncoupling it from the hook, I provide the hook with 1 the following novel Specification of LettrsPatent;

means to retain the link coupled with the The collar in the adaptation illustrated isbeveled peripherally, its diameter adjoining. the extremity of the hook being its greater daimeterand leaving a space 2' between the shank of the hook and its said free end 0 less than the "thickness of the link.

Having coupled the link with the hook,

the collar is slipped onto the end 0 and r then the cotter pin- 9 introduced to form a stop device for the collar. The collar will then prevent escape of the link from the hook, and due to its bevel there is ample room for the link without unduly increasing the size of the bend-portion of the hook.

There is this further advantage of the bevel particularly if the collar is loose on the end 0 and affords a more or less sharp edge at the outer end of its bore j, to wit, that any tendency of the link to displace the collar toward the extremity of the end resolves itself into the link camming the collar against said end 0 more or less into the position shown in Fig. 3, so that the pressure of the collar is assumed more by the end 0 than by the stop device 9. As to this feature of my invention I do not wish to be limited to the collar being beveled for it is obvious thatconvergence between itsperiphcry and the opposed part of the shank 0 of the hook is essentially the factor which causes the camming of the'collar against the end 0?. I

When the link is to be detached from the hook, it is of course only necessary to remove the cotter pin and slip off the collar.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In combination, with a link, a hook with which it is coupled, a collar slipped onto the free end of the hook, the periphery of the collar and the opposed face of the shank of the hook forming a link-receiving space converging away from the bend of the hook and of less width at its narrowest por tion than the link is thick, and a removable stop device carried by the hook between its receiving space between the shank of the extremity and the collar. hook and its said free end less than the 2. In combination, with a link, a hook thickness of the link, and a removable stop 10 with which it is coupled; a beveled collar device in said hook between its extremity 5 loosely arranged on the free end of the hook and the collar.

and having its greater diameter adjoining In testimony whereof I affix my signature. the extremity of the hook and leaving a link- ANSON E. CARLTON.
